Title: Pressure transmitting device
Inventor: KOZUTA HIDEO
IPC: G01L19/00
Filed: 1983-03-14
Abstract: PURPOSE:To prevent a fluid from flowing out in great quantities due to damage of a meter, or leakage and damage in a flow path to the meter from a pressure transmitting device, by providing a moving plate which divides into two the inside of a body which is cylindrical and whose both end parts are communicating to a pressure meter and the fluid, respectively, and also moves in the axial direction of the body. CONSTITUTION:An O-ring 5 is fitted into the circumference of a moving plate 4, and a space contained in a body 3 is divided into two by this moving plate. When a cock 02 is opened, a fluid flowing in a pipe P goes into one chamber partitioned by the moving plate 4 of the body 3. As a result, the fluid pushes the moving plate 4 in accordance with its pressure, and a pressure gauge S receives its pressure through hydraulic fluid, and displays the pressure. When damage is generated in the pressure gauge S or a pressure leading pipe 01, or the connecting part is loosened in the course of a measurement extending over many hours, the hydraulic fluid leaks from said part. When the working oil leaks, the moving plate 4 moves by being pushed by a fluid pressure, and in the end, all the hydraulic fluid is pushed out of the inside of the body 3. However, since the moving plate 4 divides the inside of the body 3 completely, it does ot occur that the fluid flowing in the pipe P flows out.

Abstract: PURPOSE:To enable controlling the concentration, shape, conductivity type, etc., of diffusion layer to make them desirable ones, by forming doped glass, a silicon nitride film, a silicon nitride protecting film, etc., and changing diffusion coefficients of impurities. CONSTITUTION:After an impurities diffusion layer forming region on a silicon substrate 1 is isolated by a field insulating film 2 of silicon oxide, a doped glass (silicone oxide) film 3 to which arsenic is added is deposited. A silicone nitride film 4 is sequentially deposited on the whole surface. After resist 5 is left at a part of the impurity diffusion layer forming region, the film, 41 exposed from the resist 5 is eliminated. After the resist 5 is eliminated and a protecting film 42 of silicon nitride is exposed, high temperature heat treatment is performed, and arsenic is diffused from the glass 3 into the substrate 1. In the region where the film 41 is eliminated, the high concentration arsenic diffuses deeply to form an N<+> type diffusion layer 7. In the region where the film 42 is left, the low concentration arsenic diffuses shallowly to form an N<-> type diffusion layer 6. Thereby the desired concentration, the shape, and the conductivity type of a diffusion layer can be controlled.

Title: Drive control circuit for image reader
Inventor: OKUMURA TAKUSHI
IPC: H04N1/028
Filed: 1994-03-14
Abstract: PURPOSE:To give a slow transfer clock in a valid period requiring image reading, to give a fast transfer clock for a non-read period not needing image reading and to increase reading speed matching the reduction of the size of an original. CONSTITUTION:A selector 14 in the usual operation selects a 1st transfer clock CCDCLK and a reset signal RS and gives the selected clock and signal to a read unit 1. Thus, the unit 1 transfers sequentially image data read by using the clock CCDCLK while a valid period signal SENS is at a high level. On the other hand, a signal CKSEL from a non-read period CKSEL generating section 13 is inverted from a low level to a high level matching the inversion of the signal SENS from a high level to a low level. The selector 14 is switched by the rising of the signal CKSEL and a 2nd acceleration transfer clock CCDCLK in place of the clock CCDCLK and a reset signal RSR are given to the unit 1. Thus, the unit 1 transfers an image at a faster speed than the clock CCDCLK when the signal CKSEL is at a high level.

Abstract: PURPOSE: To change torch angle with a simple constitution by fitting a welding torch to an F-axis by way of a rotation transmission mechanism and making the same independently revolvable about the F-axis.  
     CONSTITUTION: A pair of tactile pieces 17L, 17R contact the work 1 and if the position is correct, microswitches 21-L 1 , 21-L 2 , 21-R 1 , 21-R 2  all are OFF and assume a neutral state that they emit no signals at all. If the position is inadequate, the ON and OFF states in the microswitches vary in various ways and the signals of combinations of 10 kinds in total are emitted. At the overreturning and overshooting, suitable correction outputs are given to the X-axis and Y-axis. For the clockwise rotation direction correction and counterclockwise rotation direction correction, the correction outputs are applied to the X-axis and Y-axis while the rotation correcting outputs are being given to the F-axis 5. In this way, the rotation correction commands are so applied to the F-axis 5 that the detection neutral lines when the tracing sensor 7 make two-point contact align as normal to the column plane, hence the deviation of the arc point of the welding torch 6 does not occur; even more, the torch may be correctly directed to the weld line l by maintaining the torch angle constant.
